Working well It's amazing how many people don't read the description of the app they are downloading, especially Moto 360 users. It states it works with square watches and they still get it then one star review because it doesn't work.
Works ok but is a bit counter-intuitive The needle always point north, so it works on Sony Smartwatch 3. However, the fixed N/S/E/W bezel just serves to confuse. When I'm facing east the needle points to "W". Why not make the whole thing rotate? The way it is, you always have to rotate your wrist so that the arrow points to "N" first and then read of the compass directions from the bezel.
Doesn't work with round devices Even though it does say in the description that it's only compatible with square devices, I find that unacceptable when the UI is round anyway and Google provides all the tools necessary to maintain compatibility with both rectangular and round devices.
Moto 360 crashing The app crashes on the moto 360. I will update my review at a later date if this supports the 360
Not optimised for round devices Force closes on G Watch R and Moto 360. Looks like it isn't optimised as the main activity still has "Hello Round World!", whichcan be seen shortly before it crashes.
Not calibrated correctly. As another review said, NW shows NE and so on. Thanks for the effort. Will re-download once fixed.
